perf/x86/intel: Apply static call for drain_pebs
commit 314dfe10576912e1d786b13c5d4eee8c51b63caa upstream.
The x86_pmu_drain_pebs static call was introduced in commit 7c9903c9bf71
("x86/perf, static_call: Optimize x86_pmu methods"), but it's not really
used to replace the old method.
Apply the static call for drain_pebs.
Fixes: 7c9903c9bf71 ("x86/perf, static_call: Optimize x86_pmu methods")
